Wonderware’s WWRSLinx I/O Server
This application note is designed to help configure Wonderware’s WWRSLinx I/O Server for use with
Equustek’s DL products. Wonderware’s WWRSLinx I/O Server is designed to work with Allan-
Bradley’s RSLinx software. In order to use WWRSLinx with Allan-Bradley’s RSLinx, the version of
Allan-Bradley’s RSLinx must have OPC and DDE connectivity. RSLinx LITE does not have OPC
and DDE connectivity and will not work with WWRSLinx.
1. Configuring Allan-Bradley’s RSLinx Software
Before using Wonderware’s WWRSLinx software, Allan-Bradley’s RSLinx software must be
configured. The following sections are to help configure the communications driver, client
application, and the DDE/OPC topic configuration.
1.1 The Communications Driver
The following steps are to help configure the communications driver needed to allow RSLinx to
communicate with your DL product. Start up your RSLinx software before beginning the

your DL product to communicate with. If using a DL4500 product, refer to the DL4500
Hardware Quick Start for setting up a virtual COM port using the ComPort Redirector.
Once all the settings are chosen, click OK. You should now see in the RSWho window the
communication driver that was just set up. Put a checkmark beside Autobrowse at the top
left corner of the window and all the nodes on your network should appear.
1.2 Client Application Configuration
This section deals with setting up the client applications so that Wonderware’s WWRSLinx can
communicate with Allan-Bradley’s RSLinx software.
From the top menu bar, select Communications and then choose Configure Client
Applications. The Configure Client Applications window should appear as shown below.
Under the INTERCHANGE Port Mapping tab, select the communications driver that was
created in section 1.1. Once this has been selected, click the OK button.

2. Configuring Wonderware’s WWRSLinx Software
After Allan-Bradley’s RSLinx has been configured, the next step is to configure Wonderware’s
software. The following sections are to help in configuring WWRSLinx.
2.1 Setting up WWRSLinx
This section is to help in configuring WWRSLinx to be used with Allan-Bradley’s RSLinx
software. Start your WWRSLinx software before continuing with the following steps.

Once this window appears, fill in the following information. For the Topic Name, use the
same name for the topic that was created in Allan-Bradley’s RSLinx. Under the PLC
Family, select the type of device you are connecting to. For the Networking Addressing,
select Direct for the Connect Type, 1KT:0 for Port Mapping, and the station node address of
the PLC for the station. After these settings are finished, click OK.
The Topic Definition window from step 1 will reappear with the new topic that was just
created. Click the Done button to close this window. WWRSLinx is now setup.
2.2 Setting up the WWClient software
This section is to help setup the WWClient to communicate with WWRSLinx. Open the
